1.3 Insulation
This section includes tapered insulation, found in each product type/manufacturer shown below.
1.3.1 Composite Board Insulation
Composite board roof insulation products consist of an insulation bonded with another insulation and / or a variety of other products (typically fibreboard, perlite, membranes, etc.) to form a unified, multi-layered insulation board. The top and bottom surfaces of the board may be impregnated and / or coated with asphalt (or other binders), and covered with facing materials such as roofing felts, foils, kraft paper modified bituminous membranes, etc.
The properties and performance of composite board roof insulation varies with the components of the board. Generally, the boards are manufactured to provide some of the following properties and advantages:
- Compatible with asphalt,
- Resistant to thermal conductivity,
- Resistant to fire,
- Resistant to the effects of moisture,
- Resistant to cell deterioration (durable),
- Resistant to impact, and / or
- Unaffected by asphalt application temperatures (no overlay may be required).
The possible disadvantages and precautions involved in the use of composite board insulations include:
- Complexity of manufacture and dissimilar materials,
- Sometimes expensive, and
- Limited availability
- MF - Protect Board Composite - Non-combustible mineral
- Xpress Board - Non-Combustible Mineral Wool Insulation with Factory Applied Base Sheet
1.3.2 Extruded Expanded Polystyrene Foam (XPS)
(See also Expanded Polystyrene Foam and Protected Membrane Roof Assemblies)
Molten polystyrene and a blowing agent HCFC (142B) are mixed, under pressure, in an extruder. As this solution is extruded through an orifice into ambient temperature and controlled conditions, the blowing agent vapourizes causing the polystyrene to expand approximately 30 times its original size. The continuous extrusion process produces boards with a surface “skin” and closed cell structure and, for this reason, has been used extensively for protected membrane roof assemblies. The rigid insulation boards are expanded to a specific thickness during manufacture and have an approximate density of 32 kg / cu. m (2 lb / cu.ft).
Extruded expanded polystyrene foam roof insulation is combustible and, when used on steel decks or over a roof that is subject to fire exposure from below, a fire-rated underlayment or thermal barrier (such as gypsum board) may be required between the roof deck and the insulation (consult Building Code and insurance requirements).
Extruded expanded polystyrene roof insulation is manufactured to CAN / ULC-S701 standard and is currently available in three types (depending on physical properties) and in four forms, as follows:
- Type 4 for use on conventional or protected membrane roofing systems
- Type 4 with a factory-applied latex-modified concrete topping for protected membrane roofing systems
- Type 3 for use on conventional roof systems
- Type 2 for use on conventional roofing systems [density of 24 kg / cu.m (1.5 lb / cu.ft)]
Extruded polystyrene roof insulation provides the following properties and advantages:
- Compatible with asphalt
- Resistant to the effects of moisture
- Resistant to cell deterioration (durable)
- Resistant to impact
- Resistant to thermal conductivity
- Stable K-value
The possible disadvantages or precautions involved in the use of extruded polystyrene roof insulation include:
- Flammable (combustible)
- Affected by solvents (i.e. adhesives and cleaners used for single ply membranes)
- Heat sensitive [requires an insulation overlay, such as fibreboard, to prevent “melting” (burnouts) from hot asphalt]
- Will not retain nails (requires screws and plates)
- Dimensional instability may result from improper curing at the factory

DESCRIPTION
The roofing assembly / material information published in the RCABC Roofing Practices Manual does NOT represent a complete set of the manufacturer's published data, nor does it represent a detailed specification. The preparation of a detailed specification is the responsibility of the design authority.
Tech-Crete™ insulated roof panels are 600 mm (2 ft. X 4 ft) composite panels of extruded, expanded, Type 4 CAN/ULC-S701-97 / CGSB-51.20-M87 polystyrene foam, with a factory applied 9.5mm (3/8”) latex modified concrete topping. They are designed as lightweight, self-ballasted, interlocking insulated panels for loose application on top of well drained roof membranes in a low-slope, protected membrane roof assembly.
Tech-Crete panels are tongue and grooved on the longitudinal sides, with a butt edge on the lateral ends. Each board weighs minimum 16.3 kg (36 lb.) creating an insulated panel assembly of about 22 kg/m² (4.5 lb/ft². Panels are available in standard thickness of 50 mm (2”) and 100 mm (4”). In addition, 75 mm (3”) thick panels are available as special order.
BASE INSULATION
The base insulation is Dow Roofmate*, a superior moisture resistant material (absorption less than 1%) with a high thermal resistance value of 0.88 (R 5.0 per inch.), and high compressive strength of 240 kPa (35 psi).
CONCRETE TOPPING The latex modified concrete topping is available in two standard colours, both with a relatively smooth surface:
- CTI (Concrete Topped) Insulated Roof Panels are manufactured as a standard concrete grey colour.
- SRI (Solar Reflective) Insulated Roof Panels are manufactured with a full depth white concrete topping.
PERFORMANCE
Latex modified concrete is very durable and chemically resistant. It can be cut with a masonry saw.
- Concrete topped insulation roof panels can accept occasional maintenance foot traffic, however, they are not intended for use as a patio, plaza deck or construction platform.
- As with other cementitious products, concrete topped insulation roof panels can become stained by efflorescence if stored unprotected for extended periods. This efflorescence will not be so obvious on SRI panels, however, care in scheduling and handling is required to ensure the white topping remains clean.
- Concrete topped insulation roof panels are compatible with most commonly used membranes, however, in some cases a slip sheet between membrane and insulation is required to minimize cracking of the concrete topping.

1.3.3 Expanded Polystyrene Foam (EPS)
(See also 3.6.5 Expanded Extruded Polystyrene)
Third Party Certification: RGC welcomes and accepts the industry recommendation presented by all EPS manufacturers currently active in the B.C. market to require third party certification of the EPS products meeting CAN / ULC-S701-97 / (CAN / CGSB-51.20-M87) requirements. It is understood that such a certification program requires annual inspections / recertification by an independent testing lab.
Molten polystyrene and a blowing agent are mixed and formed into uniform closed-cell structures (“beads”). These are later expanded up to 40 times by steam in a pre-expander. (The amount of expansion determines the density and, therefore, the thermal conductivity of the final product.) The expanded beads are stabilized in curing bins, fused into a billet in a block mold, and cut into the desired size, shape and thickness. This process produces rigid boards of interconnecting closed cells of densities varying from 16 to 48 kg / cu.m (1 to 3 lb / cu.ft). Expanded polystyrene insulation is commonly referred to as “beadboard” or “popcorn”.
Expanded polystyrene roof insulation is presently manufactured to the CAN / ULC-S701-97 / (CAN / CGSB-51.20-M87) standard and is available in four types, depending on the physical properties of the material. Basically, the strength (tensile, compressive, flexural, and shear) and thermal resistance properties increase, and the water vapour permeance and water absorption properties decrease from Type 1 to Type 4. (For Type 2 and Type 4 see also Section 3.6.5 Extruded Expanded Polystyrene). Note: Type 4 is usually, if not always, extruded.
Expanded polystyrene foam roof insulation is combustible and, when used on steel decks or over a roof that is subject to fire exposure from below, a fire-rated underlayment or thermal barrier (such as gypsum board) may be required between the roof deck and the insulation (consult Building Code and insurance requirements).
Expanded polystyrene foam roof insulation provides the following properties and advantages:
- Compatible with asphalt
- Resistant to the effects of moisture
- Resistant to cell deterioration (durable)
- Resistant to impact
- Resistant to thermal conductivity
- Stable K-value (the thermal conductivity does not change with aging)
The possible disadvantages or precautions involved in the use of expanded polystyrene roof insulation include:
- Flammable (combustible)
- Affected by solvents (i.e. adhesives and cleaners used for single-ply membranes)
- Heat sensitive [requires an insulation overlay (such as fibreboard) to prevent “burnouts” from hot asphalt]
- Will not retain nails (requires screws and plates)
- Dimensional instability may result from improper curing at the factory.

Polyisocyanurate is a closed-cell rigid foam material. The insulation boards are manufactured with asphalt-saturated felt, glass fibre or acrylic facer sheets on the top or bottom of the foam core. In some cases the foam core is reinforced with glass fibre or acrylic to provide additional fire resistance and greater dimensional stability.
Polyisocyanurate foamboard roof insulation is presently manufactured to two standards:
- CAN / ULC S704-01 (CGSB 51-GP-21M) applies to unfaced polyisocyanurate rigid insulation boards intended for applications where the continuous use surface temperature does not exceed +110°C (+230°F). This standard establishes one type (Type 4) and three classes (Class 1, 2 or 3) of polyisocyanurate insulation. The type is determined by the physical properties of the material and the class is determined by its surface burning characteristics.
- CAN / ULC S704-01 (CAN / CGSB-51.26-M86) applies to faced polyisocyanurate rigid insulation boards intended for applications where the continuous use temperature is within -60°C to +80°C (-76°F to +176°F). This standard establishes four types (Type 1, 2, 3, or 4), four facing categories (Facing 1, 2, 3, or 4), and two surface burning characteristic classifications (surface burning characteristic “a” or “b”). The type is determined by the physical properties of the material, the facing is determined by the product the insulation is foamed between, and the surface burning characteristic is derived from the final product's flame spread classification. RGC Guarantee Standards require that polyisocyanurate insulation manufacturers clearly identify the manufacturing date on product labels.
Polyisocyanurate insulation provides the following properties and advantages:
- Compatible with asphalt
- Compatible with roof system components
- Resistant to the effects of moisture
- Resistant to cell deterioration
- Resistant to impact
- Resistant to thermal conductivity
- Resistant to fire
- Resistant to thermal cycling (dimensionally stable)
- Unaffected by hot asphalt
- Retains mechanical fasteners
The possible disadvantages or precautions involved in the use of polyisocyanurate foam insulation include:
- Requires an insulation overlay (fibreboard or retrofit board) to prevent potential asphalt blistering
- Aged thermal resistance Long Term Thermal Resistance (LTTR) tested to CAN / ULC -S770 should be used for design calculations. Refer to RPM Section 3.6.1.1 quick reference chart for thermal resistance values.
- Felt skin may change dimensionally if exposed to weathering (provide protection prior to installation)
- Heavy equipment may compress insulation, causing deflections and de-bonding of the membrane
- Will not retain nails (requires screws and plates)

1.3.5 Fibreboard Roof Insulation
Fibreboard insulation is composed of wood, cane, or other vegetable fibres and waterproofing binders. A water slurry containing the wood fibres and waterproofing binders is deposited onto a moving screen. The water drains through the screen and the remaining mass is heated in an oven or dryer to produce the finished product. Fibreboard roof insulation is produced in several forms:
- Plain
- Impregnated with asphalt or petroleum based paraffin
- Coated with asphalt
Fibreboard Roof Insulation that is adhered in a roof assembly with hot asphalt or asphaltic-based adhesives must have an asphalt coating on the top and bottom surfaces (minimum coated two sides) to meet RGC Guarantee Standards. Fibreboard for use as roofing insulation is manufactured to meet or exceed the requirements of CAN / ULC-S706 (Insulating Fibreboard), Type I (Roof Board).
Fibreboard roof insulation provides the following properties and advantages:
- Compatible with asphalt
- Compatible with most roof system components
- Resistant to thermal conductivity
- Resistant to cell deterioration (durable)
- Resistant to impact
- Resistant to thermal cycling (dimensionally stable)
- Unaffected by asphalt application temperatures (no overlay required)
- Stable K-value (the thermal conductivity does not change with aging)
- Retains roofing nails
The possible disadvantages or precautions involved in the use of fibreboard insulation include:
- Flammable (Combustible)
- Absorbs moisture (protect from the effects of weathering)
- Low thermal values
- Organic in nature and will rot on exposure to moisture.

1.3.6 Perlitic
Perlite ore is a volcanic glass with a natural water content characteristic. When this ore is heated to approximately +930oC (+1700oF) the water vaporizes and the ore expands into glass spheroids. The expanded perlite ore may be mixed into a water slurry formulation containing cellulose fibre, a small amount of asphalt, and sometimes starch. The slurry is then dried into boards and cut to size. The top surface is usually treated to minimize bitumen absorption.
Perlitic roof insulation provides the following properties and advantages:
- Compatible with asphalt
- Compatible with most roof system components
- Resistant to thermal conductivity
- Resistant to fire
- Resistant to impact
- Resistant to thermal cycling (dimensionally stable)
- Unaffected by asphalt application temperatures
- Stable K-value
- Retains roofing nails
The possible disadvantages or precautions involved in the use of perlitic roof insulation include:
- Absorbs moisture (protect from the effects of weathering)
- Heavy equipment may compress boards causing possible debonding of the insulation from the deck
- Extremely friable (crushable); proper compounding and correct grading is important
- Relatively low thermal values.

FESCO BOARD
Fesco Board is a homogeneous board composed of expanded perlite, a volcanic ore, blended with selected binders and fibers. The perlite particles are subjected to intense heat, which causes them to expand approximately fifteen times their original size. The resulting glass-like beads contain air cells, which provide high insulating efficiency.
The top surface of Fesco Board is sealed with Top-Loc coating to ensure positive adhesion of a built-up or modified bitumen membrane. The minimum recycled content is 25% by weight.
Fesco Board has excellent fire resistance and is approved for use in Factory Mutual approved constructions. When applied over rigid decks, Fesco Board’s high laminar tensile strength resists damage from on-the-job and maintenance traffic, offers an excellent substrate for all roofing membranes, and effectively bridges flute openings in metal decks. Because of its perlite composition and low water absorption rates, Fesco Board is dimensionally stable.
| Thermal Resistance | RSI = .49 / 25 mm (R value = 2.78 / inch) | ||
| Uses | Fesco Board is a rigid, thermal roof insulation for use in built-up, modified bitumen and some single ply roofing systems. It may be applied using hot bitumen and / or mechanical fasteners. It may be used as a primary or overlayment board. | ||

NVS and Insulcel are composite systems that combine the unique properties of Lightweight insulating concrete (LWIC) and premium expanded polystyrene (EPS) foam insulation. The polystyrene insulation board can be installed in thicknesses necessary for high insulation values and in a stair stepped fashion, facilitating a positive slope to drain.
Poured 25 mm (1") for NVS and 50 mm (2") for Insulcel thickness over EPS insulation, these LWIC systems have been engineered for use over non-slotted or slotted galvanized corrugated metal decks (Insulcel), structural concrtete substrates and, where appropriate, over existing roofs in recover applications. These systems provide high performance solutions to industry concerns that include moisture resistance, high compressive strength, dimensional stability, fire and wind resistance, stable R-values and environmental safety. As a reusable resource LWIC also provides LEED values and is re-roofable.

1.4 Insulation Coverboards
Insulation coverboards are installed over insulation, when required by the RoofStar Guarantee Standards. For Guarantee Standards concerning Insulation Coverboards, refer to C6 in this section of the RPM.
Insulation overlays are used to separate the roof membrane from the primary insulation, usually for one of two reasons:
- to prevent the insulation from affecting the performance of the roof membrane
- to prevent the roof membrane and / or the method of application from affecting the insulation
The insulation can affect the performance of the roof membrane in the following ways:
- the insulation may be incompatible with the membrane, resulting in a loss of physical properties
- different coefficients of thermal expansion may result in membrane splits / cracks.
The roof membrane and / or the method of application can affect the insulation in the following ways:
- the insulation may not be capable of withstanding asphalt application temperatures and may “burn-out”
- some insulations will not accommodate direct torch-applied membranes
- insulations that are too “soft” may result in delamination or damage to the membrane or insulation when exposed to heavy loads or traffic
- the solvents and adhesives used for flexible membranes may adversely affect the insulation.
NOTE: All hot asphalt-adhered asphaltic membranes (built-up roofing, modified bitumen, etc.) require an insulation overlay over heat sensitive insulations and heat insensitive foamed insulation. RGC Guarantee Standards for heat sensitive insulations require a two-layer overlay board for a five (5) or ten (10) year Guarantee. RGC requires the use of a two-layer overlay board over heat sensitive insulations in all cases, and also requires a single-layer overlay board application over heat insensitive insulations for all hot asphalt-adhered membranes. For single-ply, non-asphaltic membrane roofing systems, the membrane manufacturer should be consulted for proprietary options.

1.5 Membranes
Styrene butadiene styrene (SBS) polymer modifiers are “thermoplastic elastomers”. They are elastomers, which behave similar to both thermoplastics and thermosets (or “elastomerics”). Thermoplastics soften with heat and harden when cooled, no cross-linking (vulcanization) of molecules occurs, and they tend to exhibit “plastic” properties. Thermosets are materials in which cross-linking of the molecules occurs and they tend to exhibit “elastomeric” or rubber-like properties.
Simply stated, flexible polybutadiene “chains” interconnect with the glass-like polystyrene “blocks” and, when cooled, the resulting network behaves as if the molecules were cross-linked. The process is repetitive in that the networks may be disrupted by heat or solvents but will reform upon cooling or removal of the solvents.
Bitumens modified with SBS can display improved physical and mechanical properties. The improved properties are only possible if the SBS polymer is properly dispersed within a suitable bitumen. A well dispersed, homogeneous polymer mixture will form a continuous rubber network throughout the bitumen.
SBS modification of bitumens can impart the following changes in properties:
- increased softening point
- improved low temperature flexibility
- greater elasticity
- improved aging characteristics.

Country of Origin: U.S.A.
- Year First Installed
- BC: 1998
- Canada: 1993
- Foreign: 1993
DESCRIPTION
Firestone developed prefabricated sheet membranes in 1987 and introduced SBS Modified Bitumen’s in 1991, producing an elastomeric blend with exceptional elongation recovery characteristics. Reinforcing mats consisting of polyester, fibreglass and a combination thereof, are saturated and coated with SBS elastomer modified bitumen to produce roof membranes designed for use in a variety of roof systems. Firestone manufacturers a variety of membranes, each of which is designed to meet the requirements of a variety of roof constructions. The “SBS” and “SBS FR” membrane series are designed to meet the structural, climatic and design needs of a range of applications. These membranes are available with a variety of surfacing materials including; ceramic granules, polypropylene film or sand. Depending on the back surfacing, the membranes may be installed in hot asphalt, in asphalt cold process adhesive, by heat welding or peel and stick self-adhesive. Ceramic granules for cap sheets are available in several colours. If high reflectivity is required, UltraWhite membranes are covered with granules having an initial solar reflectance of 0.72 and an initial thermal emittance ranging from 0.84 to 0.92. The solar reflectance index (SRI) of the UltraWhite membranes range from 87 to 89 as per ASTM E 1980-01.
- PART 1 - GENERAL
- The roofing assembly / material information published by the RCABC Roofing Practices Manual does NOT represent a complete set of the manufacturer’s published data, nor does it represent a detailed specification. The preparation of a detailed specification is the responsibility of the design authority.
- 1.1 SYSTEM DESCRIPTION
- .1 Two-ply roof membranes: The first ply consists of a base sheet, which may be applied in hot asphalt, asphalt cold process adhesive, fully heat welded, mechanically attached or self-adhered with a heat welded cap sheet. The second ply consists of a cap sheet applied in hot asphalt, cold process adhesive or by heat welding.
- 1.2 COMPOSITION
- .1 SBS Compound: When a compatible bitumen is modified by the addition of SBS polymer, the combination provides the desirable properties necessary to ensure the long term performance of the completed roof system. Compatibility of the components, proper mixing and finished product preparation are ensured by production quality control and follow-up testing which ensures long term performance. These properties may be obtained only with a suitable SBS / bitumen compatibility and proper preparation.
- The compound in a roofing sheet provides:
- Waterproofing
- Elasticity
- Aging performance
- Flexibility
- .2 Reinforcement: The reinforcement of an SBS modified sheet provides enhancement to the compound. Polyester mat provides puncture resistance, toughness and dimensional stability upon which an SBS roof system depends for performance. A roof system relies upon the combination of compound flexibility and reinforcement toughness to resist hail and foot traffic damage. Polyester allows the SBS membrane to flex and recover while retaining its strength and toughness.
- .3 Aging: The aging properties of an SBS modified sheet are dependent on SBS / bitumen blend and the chemistry of the system. All roof systems experience heat exposure. Quality SBS modified bitumen blends age much more slowly than conventional blown asphalt.
- .4 Thickness: The aging properties of an SBS modified sheet are influenced by thickness. Thicker sheets age more slowly. Heat welded membranes should have a minimum back coating thickness of 1 mm asphaltic compound.
- 1.3 DELIVERY, STORAGE AND HANDLING
- .1 All materials must be stored out of the weather in a clean, dry area in the original packages with the manufacturer’s labels intact.
- .2 All materials must be stored on end at a minimum of 4ºC (40ºF) and a maximum of 60ºC (140ºF).
- .3 If materials are stored temporarily, they must be stored on end, elevated from the roof surface or the ground, on a pallet and covered by a light colored opaque tarp.
- .4 Materials stored on the roof must be stored in a safe matter not to exceed the allowable live load of the storage area.
- .5 Care must be taken when transporting and handling Firestone SBS rolls to avoid physical damage.
- .6 Isolate Firestone modified bitumen sheets from contact with waste products, petroleum products, grease, oil and animal fats.
- 1.4 SITE CONDITIONS
- .1 Slope: Roof slopes which exceed ½" in 12" (4.2%) require the following:
- .1 The building owner or the design professional intending to specify back-nailing should consider geographic location, specific job conditions, accepted area application practices and the type and grade of materials specified when creating an actual specification for a project.
- .2 When the slope of the roof exceeds ½" in 12" (4.2%) and hot asphalt attachment is specified, Firestone requires Firestone SBES Mopping Asphalt or CSA A123.4, Type III (3) asphalt be used.
- .3 Contact Firestone Roof Systems Solutions Group for additional requirements regarding roof slopes over 3" in 12" (25%).
- .4 For roof slopes up to and including ½" in 12" (4.2%), the side laps can be installed parallel or perpendicular to the slope.
- .5 For roof slopes greater than ½" in 12" (4.2%), the membrane must run parallel to the slope and be back-nailed.
- .6 For non-nailable decks and nailable decks with insulation, the cap sheet must be cut to conform to the spacing of nailers. Using capped nails, nail the end lap across the width of the sheet, with the first nail spaced ¾" (19 mm) from the leading edge of the sheet. The remaining nails are to be spaced approximately 3" (76.2 mm) on centre. The nails should be staggered across the width of the nailer. Firestone fasteners and plates may be used in lieu of cap nails. Four per end lap are required.
- .7 For nailable decks with no insulation, the cap sheet must be cut to conform to nailer spacing.

- .3 Steel decks:
- .1 Firestone recommends that the steel deck be a minimum 22 gauge (0.76 mm).
- .2 Factory Mutual Research - Approved steel decks are currently available in 22 gauge (0.0295", 0.794 mm), 20 gauge (0.0358", 0.909 mm) and 18 gauge (0.0474", 1.204 mm) thick sheet with 1.5" (38 mm) deep corrugations. The corrugations (ribs) are cold rolled in the sheets. The deck has a 6" (152 mm) module, that is, the ribs are 6" (152 mm) on centre. All fastening approvals and recommendations are based on this profile. (Approved and recommended spacings are such that the fasteners will engage the top flange of the deck). Another common configuration is 3" (76 mm) deep deck, which usually has an 8" (203 mm) module.
- .3 When mechanically attaching insulation, steel decks are required to have a fastener pullout of 300 lb. per fastener.
- .4 The Firestone base sheet or cap sheet may not be adhered directly to a steel deck. The cap sheet and / or the base sheet must be adhered to an acceptable insulation or coverboard.
- .5 On steel decks, the edges of insulation boards running parallel with the deck are required to be supported by the top flange of the metal deck. The board should have a minimum 1.5" (38.1 mm) bearing on the steel deck flange. Cantilevering insulation boards over deck flutes can fracture insulation boards, reducing the support for the membrane, making it susceptible to puncture.
- .6 If present, it is required that phenolic insulation be removed. Once removed, a visual inspection of the deck condition and other components is required. It is the building owner or his design professional’s responsibility to determine the condition of the deck. All deteriorated components must be replaced as necessary.

- PART 3 - EXECUTION
- 3.1 PREPARATION
- .1 Apply roofing materials over clean, dry surfaces in accordance with good roofing practices of the RGC.
- .2 Ensure that moisture and contaminates are completely removed from the substrate prior to membrane application.
- .3 Prime all metal flashings to be installed in the membrane and allow primer to dry prior to installation.
- .4 Use only compatible primers and adhesive, mastics or sealants.
- .5 Provide adequate protection against fire, particularly when using propane torch-applied membranes.
- .6 Torch base sheets to approved substrates only.
- 3.2 INSULATION
- .1 Mechanically fasten insulation over nailable decks, in accordance with RGC Guarantee Standards.
- 3.3 APPLICATION INSTRUCTIONS FOR A TWO-PLY SYSTEM
- .1 Beginning at the low point of the roof, apply the membrane base sheet to the substrate using a minimum side lap of 3" (76 mm) and an end lap of 6" (150 mm). Stagger end joints. Terminate the base sheet at the top of the cant strip. Do not adhere base sheet to cant strip.
- .2 Beginning at the low point of the roof, fully adhere the cap sheet to the base sheet. Side laps must be a minimum of 3" (76 mm) and end laps must be a minimum of 6" (150 mm). Position base sheet laps so that the distance between base sheet laps and cap sheet laps shall not be less than 12" (300 mm).
- .3 Stagger end laps from course to course so that at no end lap will be closer than 12" (300 mm) from the preceding and succeeding end lap.
- .4 Provide a smooth application, free of air pockets, wrinkles, fishmouths or tears.
- 3.4 JOB SITE CONSIDERATIONS
- .1 During the construction process, the roofing contractor is responsible for ensuring that all components of the Firestone roof system, including the finished areas are protected from damage, including, but not limited to:
- 1.1 Damage that may result from the continued construction process.
- 1.2 Discharges such as petroleum products, greases, oils (mineral and vegetable), animal fats and other by-products.
- 1.3 Direct contact with continuous steam or heat sources when the in-service temperature is in excess of 60ºC (140ºF).
- .2 All safety regulations required by agencies having jurisdiction must be followed.
- .3 Refer to the Firestone Technical Information Sheet "Recommended Guidelines for Working on an Occupied Building" for specific guidelines when installing adhesives or asphalt products on an occupied building.
- .4 Cold weather conditions:
- 4.1 When the outside temperature is below 4.4ºC (40ºF), installation of the Firestone roof system may required additional application precautions:
- For a minimum of 24 hours before installation, adhesives and sealants should remain in an environment between 15.5ºC (60ºF) and 26.6ºC (80ºF).
- Materials should be used within four hours of removal from a heated storage area. If materials area not used within that time period, they should be returned to the heated storage area until the temperature of the material returns to the temperature of the heated storage are. Typically, this is 24 hours.
- Certain products may be damaged when allowed to freeze. Do not use any products that have been frozen without written permission from Firestone.
- Refer to the product Firestone Technical Information Sheet (TIS) for application and temperature restrictions.
- 4.2 For additional information and guidelines, see the Firestone Asphalt Roofing Application Guide and the CRCA Roofing and Waterproofing Manual.
- 4.1 When the outside temperature is below 4.4ºC (40ºF), installation of the Firestone roof system may required additional application precautions:
- 3.5 ASPHALT PRODUCTS
- .1 Assure that all health and safety measures are followed when installing hot asphalt to protect the installers as well as the occupants of the building. Assure compliance to all building codes and safety regulations when using hot asphalt.
- .2 Asphalt for installing the flashings and / or the roof membrane base sheet, base plies and cap sheets must be Firestone SBES Mopping Asphalt or either CSA A123.4, Type III (3) or Type II (2). Asphalt selection must be suitable for roof slope. All asphalt must be tested in accordance with ASTM D 312 and be certified by the supplier that it meets the minimum requirements for the specific type.
- 2.1 Mopping asphalt must never be heated above the flashpoint temperature.
- 2.2 Mopping asphalt must never be heated above the finished blowing temperature for more than 4 hours.
- .3 Asphalt Primer: Asphalt primer must meet the requirements of ASTM D 41.
- .4 When hot asphalt is required, Firestone requires that Firestone SBES Mopping Asphalt or CSA A123.4, Type III (3) asphalt be used.
- In all SBS systems.
- Where the slope exceeds ½" in 12" (4.2%).
- .5 Asphalt properties may change when stored at high temperatures for long periods of time. Asphalt may become harder or may experience what is known as “fallback”. Fallback is the degradation of the asphalt to the point that its physical properties (i.e. softening point) deteriorate which could then cause roof slippage. To reduce the chances of fallback, the following recommendations should be implemented:
- 5.1 Use higher softening point asphalt.
- 5.2 Decrease the kettle temperature as much as possible, while maintaining the minimum application temperature.
- 5.3 Use material as quickly as possible, thus reducing exposure time.
- 5.4 Insulate all lines and equipment used to transport asphalt.

- PART 1 - GENERAL
The roofing assembly / material information published by the RGC Roofing Practices Manual does NOT represent a complete set of the manufacturer's published data, nor does it represent a detailed specification. The preparation of a detailed specification is the responsibility of the design authority.
- 1.1 SYSTEM DESCRIPTION
- .1 Two-ply roof membranes: the first ply consists of a base sheet; applied with hot asphalt, cold adhesive fully heat welded, with adhesives and heat welded seams, self-adhered with self-stick products; the second ply consists of a cap sheet applied with hot asphalt, cold adhesive or heat welding.
- 1.2 PROJECT CONDITIONS
- .1 Do not apply roofing insulation or membrane to damp deck surface.
- .2 Do not expose materials subject to water or solar damage in quantities greater than can be weatherproofed during same day.
- .3 All slopes greater than 2:12 (17%) require back-nailing to prevent slippage of the ply sheets. Use ring or spiral-shank one (1) inch (25 mm) cap nails, or screws and plates at a rate of one (1) fastener per ply (including the membrane) at each insulation stop. Place insulation stops as per RGC Guarantee Standards (Section 2.1.1) On non-insulated systems, nail each ply directly into the deck at the rate specified above. When slope exceeds 2:12 (17%), install all plies parallel to the slope (strapping) to facilitate backnailing. Install four (4) additional fasteners at the upper edge of the membrane when strapping the plies.

- .1 Asphalt: Roofing asphalt conforming to ASTM D312-78 Type 4, CSA A 123.4 M < 1979 Type # on slopes less then 1:24 (1/2” in 12’) (4%).
- Part 3 – EXECUTION
- 3.1 PREPARATION
- .1 Ensure membrane substrate is rigid, dry, smooth, compatible, free of fins and sharp edges, and clean of all
- .2 Ensure all openings, walls, and projections through the roof are firmly affixed and cant strips, reglets and nailing strips are in place.
- .3 A thermal barrier may be required between the roof deck and some insulations. Building code and insurance requirements to be identified by design authority.
- 3.2 PRIMER
- .1 Prime wood, concrete, and metal surfaces to be directly adhered with bituminous membranes; allow to dry.
- 3.3 APPLICATION INSTRUCTION FOR A TWO SYSTEM
- .1 BASE SHEET INSTALATION (TWO PLY SYSTEM) HOT OR COLD
- A) Base sheet: Install one (1) SBS base sheet in twenty five (25) lbs (11.3kg) per square of bitumen of cold adhesives shingled uniformly over the entire prepared substrate. Shingle in direction of slope of roof to shed water on each area of roof. Do not step on rolls until asphalt has cooled, fish mouths should be cut and patched.
- B) Lap ply sheet ends eight (8) inches (203mm).
- C) Lightly broom in base plies to assure complete adhesion.
- D) Extend plies two (2) inches (50mm) beyond top edges of cants at wall and roof projections and equipment bases.
- E) Install base flashing ply to all perimeter and projection details after membrane application.
- .2 MODIFIED MEMBRANE INSTALATION HOT OR COLD
- A) Solidly bond the modified membrane to the base layers with specified asphalt or cold adhesives at the rate of twenty five (25) to thirty (30) lbs. (11-13kg) per 100 square feet.
- B) The modified membrane roll must push a puddle of asphalt in front of it with asphalt or cold adhesives slightly visible at all side laps. Exercise care during application to eliminate air entrapment under the membrane.
- C) Apply pressure to all seams to ensure that the laps are solidly bonded to substrate.
- D) Install subsequent rolls of modified membrane across the roof as above with a minimum of four (4) inch (101mm) side laps and eight (8) inch (203mm) end laps. Stagger the end laps. Apply the modified membrane in the same direction as the previous layers but stagger the laps so they do not coincide with the laps of the base layers.
- E) Apply asphalt or cold adhesives no more than five (5) feet (1.5m) ahead of each roll being embedded.

DESCRIPTION
Hal Industries Inc. has been manufacturing asphalt roofing products for the flat roofing industry since 1974.
Asphalt available from B.C. refineries has been shown to have excellent compatibility with SBS polymers. Hal Industries Inc. uses a high-shear mixing process to blend raw asphalt with linear and branched SBS polymers. Limestone filler is then added as a thickener and conditioner and other minor ingredients are added as performance enhancers. This blend is used to saturate and coat non-woven polyester or fibreglass mat to produce a very flexible, high-quality membrane.
Cap sheets are surfaced with either mineral granules or aluminum foil on the top side and either sand or thermofusible polypropylene film on the underside. Base sheets are surfaced with sand or thermofusible polypropylene film, or a combination of these. Membranes may be installed either by the torch method or by embedment in hot asphalt.
Product designations are as follows:
- Therm-a-ply P180 series (Polyester-reinforced, moppable, torchable)
- Therm-a-ply G100 series (Fibreglass-reinforced, moppable, torchable)
- Alumatac P180 or Alumatac G100 (Aluminum foil-surfaced, moppable, torchable)
- Polymax 180 GS (Mineral-surfaced cap sheet, moppable)

- .5 Perma-board is an accepted insulation overlay for one and two layer applications where applicable.
- .6 Where a torch-applied roofing system is to be installed over Perma-board and the surface beneath the Perma-board is flame sensitive, then cover all joints in Perma-board with tape or alternately place 150 mm (6") wide Type IV fibreglass strips beneath joints, prior to torch-applying a membrane. Tape is to be HAL’s torch-applied Therma-tape.
- .7 Where tape is used to flame-proof the joints in Perma-board, use the following steps:
- Pre-torch all edges of each Perma-board sheet before installing to remove polyfilm surface layer.
- Cut tape into convenient lengths then pre-torch one side and place quickly over joint, then press or roll to adhere. Overlap end joints 50 mm (2").
- .8 Fasten Perma-board overlay using nine fasteners per board, as shown, or alternatively adhere Perma-board with hot asphalt, according to RGC Guarantee Standards, ensuring that sanded-side be placed down against the asphalt.
| 2 m (80") | ||||||||||
|
1 m (40") |
- 3.5 BASE SHEET APPLICATION
- .1 On slopes up to 1:12 (1" in 12"), install base sheet at right angles to slope, beginning at low point of roof.
- .2 On slopes exceeding 1:12 (1" in 12"), install base sheet parallel to slope, and nail upper edge at 200 mm (8") o/c with minimum 25 mm (1") headed roofing nails.
- .3 Unroll and align membrane, lap sides 75 mm (3") and ends 150 mm (6"). Always keep several rolls laid out on the roof deck ahead of the installation to permit relaxation and acclimatization to take place.
- .4 Install each aligned sheet by re-rolling approximately halfway and adhering each half alternately.
- .5 Asphalt-adhered sheet (sanded side down) (Use Type 3 or Type 4 asphalt only):
- Apply hot asphalt to the roof deck surface at its equiviscous temperature [minimum 205°C (400°F)] at a rate of 1.2 kg / m² (25 lb / 100 sq ft).Maintain a puddle just ahead of the advancing roll at all times, allowing a positive bleed-out to occur at each edge of the sheet.Never mop more than one metre ahead of roll.
- Press the membrane into the hot asphalt.
- Slit any fishmouths and press in while asphalt is still hot.Apply a patch to cover any slits by embedding the patch into hot asphalt.
- Use a roofer's torch to melt polyfilm and prepare a selvedge under each end lap.
- .6 Torch-adhered sheet (polyfilm-surfaced side down):
- Using a trigger-handled roofer's torch, heat the roll surface evenly until the polyfilm surfacing melts and a slight flow of coating occurs.Apply heat to selvedge edge of previous sheet while at the same time advancing the roll with a hooked bar.A slight bead of coating should squeeze out at the lap.
- 3.6 CAP SHEET APPLICATION
- .1 Install cap sheet in the same direction as the base sheet, starting at low point and staggering all laps.Offset the side laps from base sheet side laps by a minimum of 300 mm (12") and end laps by a minimum of 1 m (39"). Overlap at sides must be no less than 75 mm (3"), and at ends no less than 150 mm (6").
- .2 Keep several rolls laid out on the roof deck ahead of the installation to permit relaxation and acclimatization to take place.
- .3 Install each aligned sheet by re-rolling approximately halfway and adhering each half alternately.
- .4 Asphalt-adhered sheet (to sanded base sheet only):
- Apply hot asphalt to the base sheet surface at its equiviscous temperature [minimum 205°C (400°F)] at a rate of 1.2 kg / m² (25 lb / 100 sq ft).Maintain a puddle just ahead of the advancing roll at all times, allowing a positive bleed-out to occur at each edge of the sheet.Never mop more than one metre ahead of the roll.
- Roll out and press the membrane into the hot asphalt, eliminating any trapped air pockets.Avoid walking on newly-placed cap sheet until it cools.
- .5 Torch-adhered sheet:
- Using a trigger-handled roofer's torch, evenly heat the underside of the cap sheet roll and the top side of the base sheet, creating a liquid sheen on both surfaces.Advance the roll with a hooked bar, ensuring that a minimum 8 mm (3/8") bead of melted coating exudes at the lap edge.Maintain a puddle of melted coating ahead of the roll.
- 3.7 MEMBRANE FLASHING
- .1 Cut flashing membrane into suitably-sized pieces one metre wide.Allow for minimum 75 mm (3") side lap, 150 mm (6") lap onto roof deck, and 200 mm (8") up vertical surface.
- .2 Asphalt-adhered flashing: apply a full mopping of hot asphalt to the roof surface and press in each flashing sheet ensuring good adhesion.Use a hand trowel to aid in the process.
- .3 Torch-applied flashing: use a detailing torch to heat the underside of each flashing sheet and the roof surface.Press each sheet into position with the aid of a hand trowel.
- .4 Wherever practical, we recommend flashing be torch-applied rather than asphalt-adhered wherever practical.
- 3.8 PRECAUTIONS
- .1 When a torch-applied sheet is to be lapped over a granulated surface (such as end laps), always embed granules on the lower sheet with a heated hand trowel prior to making the lap.
- .2 When a mop-applied sheet is to be lapped over a polyfilmed surface (such as end laps), always torch the film on the lower sheet prior to making the lap.
- .3 Never install membranes over a surface which contains moisture.Moisture trapped between plies will cause blistering in the future.
- If a base sheet has been installed and subsequently rained-on prior to cap sheet installation, moisture may become trapped under the polyfilm surfacing.As a precaution against entrapping this moisture during cap sheet installation, torch all polyfilm surfaces at least one hour prior to installing the cap sheets.

DESCRIPTION
The main components of the roofing and waterproofing systems are bitumen modified with SBS (Styrene Butadiene Styrene) and either fibreglass or polyester reinforcement.
The system normally consists of two plies of membrane. The membrane is produced in 1 m (39") wide rolls and varies in thickness from 2 mm (0.08") to 5 mm (0.2") depending on use and reinforcement.
The membrane is constructed by coating either a fibreglass or polyester fabric, on both the top and bottom, with high performance modified bitumen. The lower surface is either sanded or receives a poly surface while the top surface is covered with granules or sand.
The system is constructed in the field by either mopping with hot asphalt, torch welding, self-adhering, mechanically fastening or cold applied adhesive. In protected membrane roofing, granule-surfaced cap sheets are normally required on flashings only, with sanded surface cap sheets on field of roof.

- PART 3 - EXECUTION
- LIMITATIONS / CAUTIONS
- Apply roofing materials over clean, dry surfaces in accordance with RGC good roofing practices.
- Use only compatible primers and adhesives, mastics, or sealants.
- Provide adequate protection against fire, particularly when using propane torch-applied membranes.
- Torch base sheets to suitable substrates only; many rigid insulations require suitable overlay. Wood fibreboard and fibrecants are not acceptable.
- PREPARATION
- Surfaces to receive membranes must be clean, dry, and primed with compatible primer as required.
- INSULATION
- Mechanically fasten insulation over nailable decks, in accordance with RGC Guarantee Standards.
- Embed insulation in a 1.5 kg / m² (30 lb / square) mopping of hot asphalt over non-nailable deck.
- Install 11 mm (7/16") asphalt-impregnated fiberboard as an insulation overlay where required by RGC Guarantee Standards.
- Install wood nailing strips on slopes exceeding 1:12 (1" in 12").
- Protectoboard is an accepted insulation overlay. In applications requiring two layers of overlay (i.e. over heat sensitive insulations), protected board is accepted as the second layer.
- Fasten Protectoboard overlay using nine fasteners per board, as shown, or alternately adhere Protectoboard with hot asphalt, according to RGC Guarantee Standards.
- ROOF MEMBRANE APPLICATION
- Asphalt-adhered: apply asphalt to substrate at a rate of 1.2 to 1.5 kg / m² (25 to 30 lb / square), at minimum 205°C (400°F) and maximum 260°C (500°F) at point of application; mop no further than 1 m (3') ahead of unrolling material; lap sides 75 mm (3") and ends 150 mm (6") unless specified otherwise.
- Torch-adhered: torch on to suitable substrates or base sheets; lap sides 75 mm (3") and ends 150 mm (6").
- Adhesive-applied: install IKO's adhesives and membranes according to IKO's printed instructions.
- Use of cant strips is recommended. Where used, install base to the cant. Where not used, install base ply to the base of vertical surfaces.
- Start at low point and, where slopes are 1:15 (3/4" in 12") or less, start at right angles to the slope; on slopes greater than 1:15 (3/4" in 12") install parallel to the slope.
- Stagger end laps minimum 300 mm (12").
- Install base sheet stripping, starting at the outer edge of parapet, across top face, down inside vertical surface, over base sheet on cant strip (if present), and out a minimum of 150 mm (6") onto “flat” portion of roof, fully bonded throughout (unless specified otherwise); apply base sheet stripping over primed flanges of installed metal accessories.
- Install membrane cap sheet parallel to base sheet, with laps of cap sheet being offset a minimum of 300 mm (12") from those of base sheet, using same side and end laps as base sheet; embed granules (do not remove) prior to bonding onto granular surfaces.
- Limit asphalt / bitumen “bleed-out” at laps on granular surfaces to a maximum of 10 mm (3/8") width.
- Extend cap sheet stripping a minimum of 150 mm (6") onto “flat” portion of roof.
- Check laps with round-nosed roofing trowel as work proceeds; reseal unbonded areas and voids; repair punctures or tears with patches of similar materials torch-welded to surface.
- Consult IKO Industries Ltd. Technical Department for recommendations on fastener type, rates and pattern for mechanically attached membranes.

- Asphalt-adhered: apply asphalt to substrate at a rate of 1.2 to 1.5 kg / m² (25 to 30 lb / square), at minimum 205°C (400°F) and maximum 230°C (450°F) at point of application; mop no further than 1 m (3' ) ahead of unrolling roll of material; lap sides 75 mm (3") and ends 150 mm (6") unless specified otherwise. Soprasphalte M is recommended for all interply mopping of membranes. Contact manufacturer for application recommendations using SEBS Modified Soprasphalte M.
- Torch-adhered: torch onto suitable substrates or base sheets, fully bond membrane; lap sides 75 mm (3") and ends 150 mm (6") or as required by the applicable system assembly.
- Adhesive-applied: install Colply Adhesive Brush / Trowel and membranes according to Soprema's printed instructions.
- Self-adhered: Membranes used in base/cap field or stripping plies in 2 ply assemblies require substrate priming with Elastocol Stick, Elastocol 350, or Elastocol Stick H2O in almost all applications. Contact manufacturer for possible exceptions.
- Use of cant strips is optional; where used, install base sheet to bottom or top of cant; where not used, install base sheet to the base of vertical surfaces. Fiberboard Cant is not acceptable except in hot mopped asphalt applications.
- Start at low point and where slopes are 1:15 (3/4" in 12") or less at right angles to the slope; on slopes greater than 1:15 (3/4" in 12") install parallel to the slope.
- Stagger end laps minimum 300 mm (12") except in systems when soldiering and seam overlays are recommended.
- Consult Soprema Inc. for membrane flashing details; where gravel stop details are utilized, mastic under the gravel stop flange is required.
- Install base sheet stripping, starting at the outer edge of parapet, across top face, down inside vertical surface, over base sheet on cant strip (if present), and out minimum of 100 mm (4") onto field portion of roof. Apply base sheet stripping over primed flanges of installed metal accessories.
- Install membrane cap sheet parallel to base sheet, with laps of cap sheet being offset minimum of 300 mm (12") from those of base sheet, using same side and end lap widths as base sheet; embed granules (do not remove) prior to bonding onto granular surfaces.
- Limit asphalt / bitumen "bleed-out" at laps on granular surfaces to a maximum of 6 mm (1/4") width; conceal excess "bleed-out" and repair damaged granular finishes with matching loose granules from manufacturer.
- Extend cap sheet stripping minimum of 150 mm (6") onto field portion of roof, extend to top inside corner of parapets, or terminate 25 mm (1") higher than base stripping on walls.
- Check laps with round-nosed roofing trowel as work proceeds; reseal unbonded areas and voids; repair punctures or tears with patches of similar materials torch-welded to surface.
- Consult Soprema Inc. for recommendations on fastener type and pattern for mechanically fastened membranes.
- Consult Soprema Inc. for specific application and use for adhesive applied systems.
